1. A communication terminal apparatus that receives using a unidirectional communication network and that transmits using a bidirectional communication network, comprising:

  • a receiving unit that receives distribution data distributed through the unidirectional communication network;

    an accepting unit that accepts transmission data to be transmitted to a distribution source of the distribution data received by the receiving unit; and

    a communication processing unit that transmits the transmission data accepted by the accepting unit to the bidirectional communication network, whereinthe communication processing unit comprises;

    a detecting unit that detects an error message concerning the transmission data from the bidirectional communication network;

    a setting unit that sets the transmission data that includes the error message detected by the detecting unit, to be new transmission data;

    an error processing unit that subjects the new transmission data set by the setting unit to a process of resolving an error corresponding to the error message; and

    a transmitting unit that transmits the new transmission data whose error has been resolved by the error processing unit to the bidirectional communication network to use the new transmission data as the distribution data from the distribution source;

    wherein the receiving unit extracts the error message from the distribution data, when the distribution data received by the receiving unit is the transmission data that has been error-processed by the error processing unit,wherein the accepting unit divides the accepted transmission data into the permissible amount for the bidirectional communication network, when the error message extracted from the distribution data by the receiving unit indicates that the capacity of the transmission data exceeds the permissible amount of the bidirectional communication network, andthe transmitting unit transmits the new transmission data that has been divided by the accepting unit.
